10 Claims.

This invention relates to cartons of the type formed by folding up the shaped and score-defined panels of a blank of any suitable and light material such as craft-board.

One of the objects of the invention is to provide a strong light and rigid shipping container.

Another object of the invention is the provision of a carton of the class described having a front panel which may be lowered for the display of the contained commodity, and which when closed forms a positive tie between the ends of the carton.

A further object of the invention is to provide the carton having the hinged front panel which ties in the ends of the carton when closed, with a lid or top having the common function when in place of keeping the front panel closed and locking the front and ends in inter-tied relation.

Still another object is to provide a carton hav-- ing hollow walled parallelepipedal ends of plural ply thickness with flat front faces against which the lateral margins of the front panel seat and having slots in said front faces receiving tongues on said front panel for tieing the front and ends together.

Another object of the invention is the provision of a carton having the parallelepipedal hollow ends in which the flat top faces of said ends are extended at the rear so as to project inwardly forming reinforcing webs with tongues interlocking through slots, with the back panel, forming rigid trihedral corners at the upper rear of said carton.

A further object of the invention is a carton having the hollow walled parallelepipedal ends as described with shelf slots through the inner panels, said slots opening in the flat front faces of the ends, to some depth so that shelves can be introduced into said slots from the front of the carton.

Still another object of the invention is the provision of a blank, so cut, scored and perforated as, when folded and secured, to form the carton Figure 3 is a plan view of the blank in which the carton is constructed;

Figure 4 is a cross section through the carton;

Figure is a horizontal section showing in detail the front and rear corner construction in the closed carton; and

Figure 6 is a perspective view illustrating the construction which forms the rigid trihedral rear corner.

Referring now in detail to the several figures and first referring to Figures 1 and 2 in which the carton is shown in assembled form, it comprises a bottom panel I, back panel 2, flanged top or lid 3 and hinged front panel 4. These as shown are all folded from an integral blank and include also the ends 5 and 6 which are of hollow construction and parallelpipedal in shape providing the flat front walls 1 and 8 and the flat top walls 9 and ID. The top walls at the rear are expanded inwardly forming reinforcing webs II and I2 terminating in tongues I3 and H! (for tongue l4, see Figure 6) which tongues protrude through slots I5 and I6 formed immediately below the line of fold between the back panel 2 and the lid 3. Figure 6 shows that the tongues are bent down against the outside rear of the back panel 2 and suitably secured thereto. The securing means here shown are staples ll, but other equivalent means such as pasting or stitching may be employed.

The top or lid 3 has a front flange ll of double construction and side flanges 44 extended at their forward ends to form tongues 45, see Figure 3. Said tongues are folded angularly into the plane of the front flange and inserted between the folds of said front flange. The two plies of the front flanges and tongues 45 are suitably secured together as by the staples IS. The front edge 20 of the front panel 4 is folded double and se-' cured in a similar manner. At opposite sides of the front edge 20 are the tongues 2| which are angularly folded and when the front panel is in raised or closed position, the tongues 2| slide into slots 22 and 23 formed in the fiat front faces 'I and 8 of the ends of the carton. 'I'rihedral corners at the upper rear of the carton formed by the juncture of the back panel 2, the ends of the carton and webs H and I2 maintain the ends of the carton in rigid perpendicular re lation both to the back and bottom of the carton. The front portions of the ends are prevented from spreading through pressure of the contents or from other causes by the interlocking relation of the front to the ends provided by the tongues 2| when they are interdigitated with respect to the slots 22 and 23.

The inner walls 24 and 25 of the ends of the carton are provided with the transverse slots 26 and 21 which extend depthwise into the front faces of the ends as at 28 and 29 so that shelves can be slidably introduced into said slots from the front of the carton when the front panel 4 is in lowered or opened position as shown in Figure 2. When the front panel is closed its lateral margins seat against the flat front faces 1 and 8 of the ends 5 and 6 and when the top or lid 3 is swung down to closed position, the front flange l1 overlaps the edge 20 of the front panel performing the dual function of holding the front panel closed and maintaining the tongues 2| in the slots 22 and 23.

The details of construction of the hollow ends of the carton may be understood from a consideration of the blank shown in Figure 3 in which it will be seen that the bottom panel I is provided with the end panels 36 and 3| which fold up on the score lines 32 and 33, that the back panel 2 is provided with the end panels 34 and 35 which fold forwardly along the score lines 36 and 31 after the back has been folded to its upright position and that the end panels 30 and 3| are provided with the inner wall panels 24 and 25 which fold inwardly along the score lines 40 and 4| after the end panels have been raised to their normal upright position, the inner wall panels folding inwardly again upon the score lines 42 and 43 when the end panels 30 and 3| are in their upright position forming the flat front faces I and 8 hitherto described. The free inner edges of the inner wall panels 24 and 25 are folded along the score lines 62 and 63 to form the fiaps 64 and which bear against the back wall panel 2 and being suitably secured thereto as by staples.

The end panels 30 and 3| are provided at their upper ends with extensions 46 and 41 slotted obliquely as at 48 and 49 to define the webs II and I2 and folded upon the score lines 50 and 5| which define the upper edges of the end panels and foldable once again upon the scope lines 52 and 53 to define the upper flat faces 9 and I0 and the flaps 56 and 51, the latter turning down inside of the parallelepipedal ends and lying in contact with the inner wall panels 24 and 25. Said inner wall panels are formed with the shallow indents 58 and 59 in which the bases of the webs II and I2 seat in the folded carton so that said webs lie flush with the plane of the tops of the ends of the container.

The rectangular apertures 60, only one of which is shown in Figure 2 are mere incidents of,

the blank construction, being the spaces originally occupied by the tongues 2|.

For purposes of ventilation, the front and back of the carton may be provided with the apertures 6|. If for any reason it may be desired to exclude light from the closed carton, the apertures 6|, also the shelves and shelf slots 26 may be omitted.

It will be understood from the above description that I have provided a display container which may have the front panel let down hingedly along its base line 66 to display the contents of the container which may be resting upon insertable shelves, that the container is of thoroughly rigid right angular construction not only by virtue of the trihedral corners at the upper rear, but also when closed by the tieing in of the forward portions of the ends by the tongues 2| and by the enveloping action of the lid 3 which closes down over the front holding it in closed position and incidentally holding the shelves against removal. It will also be understood by those skilled in the art that the invention includes not only the specific embodiment as illus trated and described, but extends to such modifications in construction and arrangement of the various panels and other parts as may be within the terms of the appended claims.
